There are a few ways you need to find and catch Pokémon in Pokémon Go. Not all of them look the same. If you're looking to catch a super sized Pumpkaboo, you can only find it in a specific way. Here's what you need to know if you're looking to catch the super size version of Pumpkaboo.
There are four types of Pumpkaboo in Pokémon Go. All of them can appear in nature and you will be able to visually see the different dimensions in the overworld, rather than catching the Pokémon and having to wait to see its dimensions. These are all Pumpkaboo dimensions and how they appear in Pokémon Go.
The super bounty is the largest version of Pumpkaboo and has the best stats. If you are planning to use the evolved form of Pumpkaboo, Gourgeist, in PvP or PvE battles, we highly recommend that you try to acquire this version and evolve it. However, the large size is only slightly different in the stats.
Unfortunately, both large and super size versions of Pumpkaboo fall under the category of "lucky" spawns. This means that players have a low chance of finding it in the wild compared to regular Pokémon spawns. The best way to increase the chances of these Pokémon appearing is to use incense and place bait on Pokéstops whenever you have the opportunity. These are good ways to lure Pokémon to your location, giving you the ability to catch these versions. But, again, it may take some time.
Pumpkaboo only appears in nature. The medium-sized Pumpkaboo is the only version that appears in raids.
